In aviation, hot and high is a condition of low air density due to high ambient temperature and high airport elevation. Air density decreases with increasing temperature and altitude. Lower air density reduces the amount of lift generated by the wings or the rotors of an aircraft, which may hamper an aircraft's performance and hence its ability to operate safely. The reduced density also harms the performance of the aircraft's engine, compounding the effect. Aviators gauge air density by calculating the density altitude.

Famous quotes containing the words hot and/or high:
“More than I, if truth were told,
Have stood and sweated hot and cold,
And through their veins in ice and fire
Fear contended with desire.”
—A.E. (Alfred Edward)
“So in majestic cadence rise and fall
The mighty undulations of thy song,
O sightless bard, England’s Monides!
And ever and anon, high over all
Uplifted, a ninth wave superb and strong,
Floods all the soul with its melodious seas.”
—Henry Wadsworth Longfellow (1809–1882)
